ABSTRACT:
An impact limit stop or crash stop control in a disc drive for setting and maintaining the limits of movement and the stopping distance of a linear or rotary actuator member which supports and moves the transducer heads for bidirectional movement between radial limits with respect to the memory discs. In one of its aspects, this crash stop control provides a low sensitivity, high precision, limit stop adjustment which sets the limits of movement of the actuator member, and which, in another of its aspects, provides a non-linear deceleration characteristic, with some frictional damping, for the actuator member in its limits of movement.
